"I got these rings when my GBB magazines were leaking on filling. After installing them, it solved the issue.

Now, I'm trying to install them on my S-Thunder grenades, and they WILL NOT go in. The shells came with no rings, and I thought it was nice I had 4 more of these rings to use up, so I could use 2 more on these grenades. Well, think again, EVERY ONE OF THEM SNAPPED.

They are not a be-all end-all solution to fill valve o-rings.

Pros: Good, if they get installed

Cons: Bad that they cannot be installed.

"Nice O-rings. They do the job they are supposed to. I have not had any O-rings break yet. I stretch them slightly by rolling them on a tooth pick before installing them.

"These O-Rings are great. I recently bought a m1892 lever action rifle and upon arrival the gun had issues with filling. Gas would just spray everywhere. I purchased these and replaced the o-ring and it is filling perfectly and shooting great. I highly recommend these o-rings for anyone that owns gas powered guns. They are very handy.

"Good product:

Pros - now I have no gas leaks during filling up the KSC G19 mag
Cons - on one mag, the o-ring - due to its thickness - caused light gas leakage. I fixed it by oiling the o-ring

You canīt go wrong with this one!

"These work well and seem to be an improvement over the stock o-rings. I'm happy with them. To install them, I just took my propane adapter (it wasn't on the propane can, obviously) and just worked it in.

Pros
Do their job
Better than stock o-rings
Look cool in your mag

Cons
Expensive for tiny rubber rings
Kinda have to be forced inside

"These o-rings fit in KJW M9 clips I had the clips o-ring fail. Install it just like in the video but before you put it on spray some silicone lube on the o-ring and the nozzle. This ikke make it very easy to install and help make it last a long time.

"Bought these O-rings for my old Glock34 mags. I thought I had to buy a new fill valve, but all they needed were filler O-rings. Make sure to use some airsoft silicone spray/oil to lube the O-ring and the fill valve; they will go on super smooth and you will not tear any O-rings.

Install them just like the video by using two tooth picks. Just add a step, and oil everything and they will slide in easier and you won't tear any. After installation, there is no leaking when filling whatsoever.

Pros:
-Nice and thick O-rings
-Universal
-No leaks at all now!

Cons:
-Just make sure to oil the O-ring

"Fantastic o-rings! If you want o rings that wont cause green gas to spray out while filling your mags this it the item for you!

Pros: Easy to install
Prevents green gas from spraying while filling
Don't fall out like other o rings do!
Red color makes i easier to see.
